Title: Innovations by Koichi Kataura
Introduction
Koichi Kataura is a notable inventor based in Shizuoka, Japan. He has made significant contributions to the field of chemical manufacturing, particularly in the production of maltitol and maltose. With a total of three patents to his name, Kataura's work focuses on developing economically advantageous processes for manufacturing these important compounds.
Latest Patents
Kataura's latest patents include a process for manufacturing crystalline maltitol and a method for producing high-purity maltose and its reduced product. The first patent outlines a process that utilizes syrup with a maltose purity of 81 to 90% as the starting material. This syrup undergoes hydrogenation in the presence of a catalyst, followed by chromatographic separation using cation-exchange resin. The result is an aqueous solution of maltitol with a purity of 94 to 99.9%. This solution is then crystallized with a seed crystal, allowing for the simultaneous production of both crystalline maltitol and a crystalline mixture solid containing maltitol.
The second patent describes a method for manufacturing high-purity maltose in a simple and economical manner. This process involves liquefaction of starch, followed by saccharification using general-purpose enzymes and further saccharification with an enzyme that hydrolyzes oligosaccharides of trisaccharide or more. Additionally, this method allows for the economical production of maltitol, the reduced product of maltose, through an extra reduction step.
